I like this idea. Not only can you offer both versions without having to do so continuously, but the Kickstarter watches could become classics, similar to the ND Longines Legend reissue.

Regarding the bracelet and clasp, I am meeting with the manufacturer in Switzerland next March so I'll be going through all the fine details. Same for the case etc.

Hard to know for sure from pics. The clasp looks big in the rendering, but it might be like, say, the Sinn U clasp IRL: that thing is thicker than many dress watches, but it balances out the brawny U divers well. I'm inclined to trust your judgement on that.
